tern of wiring. I

The construction of my connector issuch duit by grasping the cable at this uncovered point. The cables can then be grasped at another point in the conduit and the slack taken up at the connector point in' the sys-' as to provide a full unrestricted opening therethrough, the diameter of which is indicated at in Fig. 7. Thus an opening of ables the cables or wires to be inserted without any danger of tearing the insulation from the wires and causing a short circuit. The invention also enables a ready inspection of the cables to be made at the bends by simply removing the cap 19 without disturbing the base-member 10 and its attachment to the conduits. It also affords plenty of space for splicin Another important feature of this invention is that it enables a thorough ground or metallic connection between the ends of the conduits to be made by means oi the ribs,

bushing and set-nuts construction, which furnishes the means to attach the basepiece to the ends of the connector, as described.

It is to be distinctly understood that I do not limit myself to the arc-shaped form shown in the drawings, as the connector may be in the form of a T, or cross-shaped, or it may be straight, as convenience requires.

What I claim, is,

l. A connector construction for electric conduits, comprising in combination, a basemember, an inturned rib formed at its opposite ends, a conduit, bushingson the oppositely disposed inner ends of the conduits and engaging the inturned rib at each end of the connector, set nuts on the conduit and designed to bear against the outer ends of the ribs to rigidly secure the connector and conduits in place, end caps each formed with a rib to register with the ribs on the basemember, means. to secure the end'capsin place, a cap-member located between the endcaps to close the connector, and means to removably secure the cap-member in place.

2. A connector for electric conduits, comprising a base-member substantially semii circular 1n cross-section, an inturned rib at its ends, a flange or rib formed on the edges of the'basemember, cnd-cap-members, inturned ribs formed therewith and adapted to register with the inturned ribs of the base-niember, means to secure the end-capmembers to the base-member, a cap-member located between the end-cap-inember's and within the flanges on the edges of the base prising a base-member the ends of which are formed with inwardly-projecting rib-portions designed to secure the ends of the conduits thereto, end-cap-members formed with inturned ribs and adapted to register with said ribs on the base-member, means to secure the end-cap-members to the base-member, whereby when the ends of the conduits are provided with a set-nut and end-bushing, respectively, and located on opposite surfaces of the registering ribs of the base and end-cap-members, the ends of the conduits may be secured to the connector and with the space between the end-cap-members left open to draw in the cables,as described, a cap-member,- and means tosecure the same to the basemember,

i. A connector for electric conduits, comprising a base-member formed with ribs at its extreme end-portions, end-eap-members formed with ribs adapted to register with the ribs of the base-member, means to secure the cap-members to the basemember, flanges on the edges of the base-member, and a cap or cover-member located between the end cap-members and within the edge flanges, whereby when the conduits are secured to the base-member the cap-member may be removed to permit the cables to be drawn in as described.

A connector for electric conduits, comprising a base-member, inwardly projecting rib-portions integral therewith and designed to secure the ends of the conduits thereto, endcap-inoinbers formed with inturned ribs and designed to register with said ribs on the base-mcmber, said end cap members being spaced from one another on the base member leaving an open space therebetween, means to secure the end-cap-members, to the base-member, whereby when the ends of the conduits are provided with a set-nut and an end-bushing spaced from each other, as described, and located on the opposite inner and outer surfaces of the registering ribs of the base and end-capmembers, the ends of the conduits may be rigidly secured to the connector, leaving a large opening between said end cap members available for pulling in cables.

6. A connector for electric conduits comprising, in combination, a semi-circular basemember, a rib at the end thereof, a semi circular end-cap member, a rib integral therewith, means to secure the end-cap member to the base-member, whereby a conduit having spaced nuts on its end portion may be rigidly secured to the base-member, as

prising, in combination, a base-member, a rib at m end thereof, an end-cap-member, a rib integral. there-With, means to secure the end-cap member to the base-mamber, a flange on Jae said base-member and space& away from its inner su face to provide a ledge, 21 cap-member czesigned to engage said ledge to form a closed connector, as descnbeei.
